8 .2 Current and Voltage Sensors CurrentWatch ECS Series ECS Series CurrentWatch Current Switches ECS Series CurrentWatch Current Switches Product The CurrentWatch ECS Series from Eaton s electrical sector is a family of solidstate adjustable current switches, ideal for providing status information on electrical equipment. The ECS is excellent for new installations, where the conductors run through the housing, requiring no cutting. These switches are also ideal for retrofits, since split-core models can be opened to fit around existing conductors. The current switch is accurate, reliable and easy to install. The ECS can sense continuous currents from 1 to 150A and does not require any supply voltage, as the power required is induced from the monitored conductor. The output is a non-polarity-sensitive solidstate contact for switching AC and DC circuits up to 240 Vac/Vdc. This switch also includes an LED indicating two states: on and below trip point, and above trip point with contacts energized. All ECS Series switches carry an unconditional five-year warranty. For the most current information on this product, visit our web site: Any change in current can be sensed with the ECS Series. A change in current may indicate motor failure, belt loss/slippage or mechanical failure. Any of these events can cause the current to drop significantly, tripping the switch and notifying the controller.

30 .8 Current and Voltage Sensors CurrentWatch EACR Series EACR Series CurrentWatch Current Sensors EACR Series CurrentWatch Current Sensors Product Application The CurrentWatch EACR Series current sensor family from Eaton s electrical sector combines a current sensor and a True RMS signal conditioner into a single package. The EACR Series provides True RMS output on distorted waveforms found on VFD or SCR outputs, and on linear loads in noisy power environments. Available in solid- or split-core housings. For typical applications of the CurrentWatch EACR Series, see listing on this page. Why True RMS? The current waveform of a typical linear load is a pure sine wave. In VFD and SCR applications, however, output waveforms are rough approximations of a sine wave. There are numerous spikes and dips in each cycle. The CurrentWatch EACR Series current sensors use a mathematical algorithm called True RMS which For the most current information on this product, visit our web site: Typical Applications VFD Controlled Loads Monitoring VFD output indicates how the motor and attached load are operating SCR Controlled Loads Accurate measurement of phase angle fired or burst fired (time proportioned) SCRs, with faster current measurement than temperature sensors Switching Supplies and Electronic Ballasts True RMS sensing is the most accurate way to measure power supply or ballast input power integrates the actual waveform over time. The output is the amperage component of the true power (heating value) of the AC current waveform. True RMS is the only way to accurately measure distorted AC waveforms.

37 Current and Voltage Sensors CurrentWatch EGF Series.10 EGF Series CurrentWatch Current Sensors EGF Series CurrentWatch Current Sensors Product Application The CurrentWatch EGF Series from Eaton s electrical sector is a family of ground fault (earth leakage) sensors. Ground fault sensors help protect people, products and processes from damage by ground fault conditions by monitoring all current-carrying conductors in grounded singleand three-phase delta or wye systems. The EGF Series with solidstate outputs offers the benefit of reliable, longlasting solid-state switches. Solid-state design provides unlimited switch operating life, superior resistance to shock and vibration, zero offstate leakage, high switch speeds and high input-output isolation. The EGF Series with mechanical relay outputs is available in solid-core housings with a choice of NO or NC SPST latching relays and a SPDT Form C relay with auto-reset.

Contactor Zero Sequence Operating Principle In three-phase delta and wye systems, under normal conditions, current in the hot leg of a two-wire load is equal in magnitude but opposite in sign to the current in a neutral leg. As a result, the electromagnetic fields surrounding these two conductors cancel, producing a zero sum current. As Ground Fault Sensor Leakage to Ground soon as current leaks to ground (fault condition), the two currents become imbalanced and a net magnetic field results. The CurrentWatch EGF Series sensors monitor this field and trip the contacts when the leakage rises above the setpoint. Volume 8 Sensing Solutions CA E February
